Remarkably, [Bob] Woodward sleepwalked through eight years of Bill and Hillary Clinton. There he was, sitting on the second biggest story of his career -- the emerging impeachment of Bill Clinton -- and he didn't act. Travelgate, FBI Filegate, missing Rose law firm documents found in Hillary's residence, the conviction of Webb Hubble, Vince Foster's mysterious death, the endless parade of White House bimbos ... all seemed to add up to nothing in the eyes of Mr. Woodward and his colleagues at The Post.
